Will the wall of Ness wall clothes be moldy in the humid weather conditions in the south?

No, but the wall clothes are all made of wood fiber. If the air is too humid, I think so. I am now in Guangzhou, and when I return to Nantian, there are water drops on the bathroom wall. There may be some risks if there is a wall coat on the wall and the ventilation is not good. The key depends on the structure of the house. If it is north-south convection, it may be better ventilated, so it will not be moldy. If it is not convection, it may accumulate moisture in the wall clothes and breed mold. My wardrobe is the kind that is fixed on the wall now. When I return to Nantian, mold will grow in it.
